Abstract

um aparelho para estimar uma propriedade de uma formação de solo e um fluido de furo de poço inclui um transportador configurado para ser disposto em um furo de poço, e um conjunto de medição de nêutrons pulsados que inclui uma fonte de nêutrons pulsada configurada para emitir nêutrons no furo de poço e na formação de solo, e um detector de raios gama. o aparelho também inclui um conjunto de medição de densidade de fluido incluindo o detector de raios gama e uma fonte de raios gama configurada para irradiar um fluido de furo de poço com raios gama. o detector de raio gama é posicionado em relação à fonte de raio gama, a fim de detectar tantos os raios gama resultantes de interações de nêutrons quanto raios gama emitidos do fluido de furo de poço em resposta à irradiação da fonte de raios gama. o aparelho inclui ainda um processador configurado para diferenciar um espectro de raios gama de nêutrons pulsados associado às interações de um espectro de raios gama de densidade.apparatus for estimating property of a soil formation and wellbore fluid includes a conveyor configured to be disposed in a wellbore, and a pulsed neutron metering assembly that includes a pulsed neutron source configured to emit neutrons. wellbore and soil formation, and a gamma ray detector. The apparatus also includes a fluid density measuring assembly including the gamma ray detector and a gamma ray source configured to radiate a gamma ray well bore fluid. The gamma ray detector is positioned relative to the gamma ray source in order to detect both gamma rays resulting from neutron interactions and gamma ray emitted from the borehole fluid in response to gamma ray source irradiation. The apparatus further includes a processor configured to differentiate a pulsed neutron gamma ray spectrum associated with interactions of a density gamma ray spectrum.
